First, I'm a junior in college. A college better than yours.
Second, I didn't say minimum wage wasn't necessary. I simply pointed out the simplicity of thought in the original posters post and how this "revelation" does not justify a thread devoted to it. This graph simply shows what happens when minimum wage is higher than market equilibrium.
Third, Working for $4 an hour is better than not working. True its not better than reaping the benfits of my tax dollars in the form of welfare, but it is better than being unemployed. That said however, in most industries, higher minimum wages cause companies to develop greater cost cutting measures which in turn leads to innovation. But there is still a sizeable chunk where workers are groslly overpaid. What should happen is variable minimum wage that is dependent on age/family/etc similar to taxation.
